Re: [Databionic-ESOM-User] data behind best-matches

[Irene K. <ir...@cb...>]

Thank you Fabian,
Let me try to explain it a bit better. At the end of the training I end up
with a map with best-matches colored as class 1 and best-matches colored
class 2. However, if I select an area that contains only best-matches of one
color, I can see that it contains compounds of both classes (so, I guess
that the color depends on which of the two has the majority). So, I want to
see how many of the compounds of class 2 are found under best-matches
colored as class 1 (and vice versa). Or, in other words, how many mixed
neurons my map has and how many compounds of each class are found in the
mixed neurons. 
If I do classification of the same dataset on the trained map and then save
the .cls file, this file is exactly the same as the original one. And the
only new file that is created during the classification is a projected.bm,
with the coordinates of the dataset on the map, which of course is the same
as the original .bm file, as I am using the same dataset. Am I doing
something wrong here?

best,
Irene

Irene,

I'm not sure if I understand correctly. If you have predefined classes,
you already have the assignment of data examples to classes in the *.cls
file you loaded.

If you create a new classification based on a trained ESOM you can also
save this to a *.cls file that stores data example id <-> class if pairs.

Note, that ESOM training does not make use of any prior class information
as it is an unsupervised algorithm.
